This is a product specification and technical requirements document for a 72-inch High Density Polyethylene (HDPE) pipe procurement in South Carolina. The document outlines comprehensive technical specifications for HDPE pipe materials, including requirements for pipe dimensions, wall thickness, pressure ratings, and material composition standards. The specification establishes that pipes must comply with ASTM D3350 standards for HDPE compounds and meet minimum requirements for tensile strength, elongation, and environmental stress crack resistance. The document specifies performance criteria including hydrostatic design basis (HDB) ratings, long-term pressure ratings, and temperature derating factors applicable to the pipe's intended use in water transmission and distribution systems.

The technical requirements address manufacturing standards, testing protocols, and quality assurance procedures that bidders must meet. The specification includes requirements for pipe marking, certification documentation, and factory inspection procedures to ensure product compliance prior to delivery. Additionally, the document establishes dimensional tolerances, crush strength requirements, and specifications for pipe ends, including plain end and bell end configurations as applicable. Bidders are required to provide detailed product certifications, mill test reports, and third-party validation demonstrating compliance with all stated specifications before contract award consideration.
